Single Row Cylindrical Roller Thrust Bearings 81276 M

Single Row Cylindrical Roller Thrust Bearings 81276 M

The 81276 M is a single-row cylindrical roller thrust bearing with a 380mm bore and 520mm outer diameter, built to handle heavy loads. Made from chrome steel, it supports dynamic radial loads up to 468000 lbf and operates smoothly at speeds up to 500 RPM.

Its machined brass cage ensures durability and reduces friction, while the precise tolerances (-0.040mm to 0 for bore) guarantee a secure fit. The bearing works reliably in temperatures ranging from -30°C to 110°C.

This model is interchangeable with SKF bearings, making it a practical choice for replacements. Ideal for heavy machinery, industrial equipment, or applications where high thrust loads are common.

Weighing 75kg, it’s a robust component designed for long-term performance. Compliant with RoHS and REACH standards for safe and sustainable use.
